Abstract (en)

[origin: EP4033832A1] Disclosed are a method and apparatus for determining a sidelink feedback resource, and a terminal and a storage medium. The method comprises: a first terminal acquiring sidelink feedback resource configuration information, and determining a sidelink feedback resource set according to the sidelink feedback resource configuration information; the first terminal acquiring a first parameter set; the first terminal determining a sidelink feedback resource from the sidelink feedback resource set according to the first parameter set; and the first terminal sending sidelink feedback information to a second terminal on the sidelink feedback resource. In the solution of the present invention, a first terminal determines a sidelink feedback resource from a sidelink feedback resource set according to a first parameter set, such that a specific sidelink feedback resource of the first terminal is specified, and the first terminal sends sidelink feedback information to a second terminal on the sidelink feedback resource, thereby improving the reliability of communication between the first terminal and the second terminal.
